What symptom is NOT commonly associated with lead poisoning?

Lead poisoning can present with a variety of symptoms, many of which are neurological or cognitive in nature due to the toxic effect of lead on the brain and nervous system. Clumsiness, seizures, and drowsiness are indeed commonly associated with lead exposure. Clumsiness arises from cognitive effects and motor function impairment, while seizures can occur as a severe consequence of lead toxicity. Drowsiness may be observed due to overall neurological involvement.

Headache, while it may be a general symptom resulting from various conditions, is not specifically characteristic of lead poisoning. Although it can occur in some cases, it is not a hallmark symptom associated with the condition. The more pronounced implications of lead toxicity are seen in motor skills, seizure activity, and altered levels of consciousness, making headache a less defining symptom in the context of lead poisoning.
